Self–powered (PFG) sensor technology that provides zero–maintenance health and usage monitoring systems capable of scavenging energy for sensing, computation and storage from embedded strain variations.
Piezonix’s sensor-to-circuit integrated system can collect, compute and store historical statistics of a structure’s strain-rate and levels at operational power limits not possible with any competing heath monitoring sensor technology. By operating on picowatts to nanowatts of power, Piezonix’s self-powered sensors can function continuously by scavenging energy from, for example, a miniature piezoelectric transducer.
